When a honey bee sucks up nectar from a flower though its proboscis, some of it goes into the main stomach to be used as food for energy. The remaining goes into a special stomach to be processed into honey.

Due to their immense size, elephants produce a lot of body heat. Thankfully, much of it radiates out through veins in their large floppy ears. An elephant can lose as much as 48 degrees Fahrenheit (9 degrees Celsius) through its massive ears.

Don't go by their cute appearances – poison dart frogs are some of the deadliest animals on earth. A single poison dart frog possesses enough venom to kill 10 adult men. Sometimes, animals die simply by touching a spot where a dart frog had just been.

The smallest bird in the world, the hummingbird is immensely fast and swift and can fly backward, upside down and even sideways. However, their legs are too weak and tiny to support walking. The most they can manage is to shuffle sideways.

Male gentoo penguins look for the smoothest, shiniest pebble to present to females of their choice. If the female accepts, she takes the pebble and places it in her nest, accepting the male as her mate.

Spider silk, though thinner than human hair, is shockingly stronger than steel and as strong as nylon of the same width. It can also stretch up to 30 percent of its original length without breaking. A 2-inch-thick rope made of a spider thread can even stop a Boeing 747, research claims.

This is their way of coping with three months of constant summer sunlight followed by another three months of winter darkness. During summers, reindeer eyes reflect most of the light through the retina and thus appear golden in color. In winters, enhanced night vision kicks in and a layer of tissue appears behind the retina making it look blue.

The electric eel can deliver enough electricity to knock down a fully grown horse. One of the most formidable predators in the animal kingdom, an electric eel's body has specialized cells that can emit 600 volts of current.

Cockroaches can survive decapitation because they breathe through openings called spiracles on their body, which are not controlled by their brain. A headless cockroach will die after about a week out of thirst and hunger.

A turtle's gender is not determined by chromosomes but the ambient temperature of the eggs. This has become a matter of concern in light of global warming with a threat of an all-female population and extinction.

African wild dogs are known for being particularly nice to the young, old and injured of their pack. They bring back food for the old and injured, nourish them and take care of their wounds by licking them.

Alpacas are gentle and docile animals and enjoy each other's company. When kept alone, they become sick and eventually die. Therefore, it is advised that alpacas must always be bought in pairs if not an entire herd.

Relative to their body size, chameleons have the longest tongues in the animal kingdom. The reptile keeps its tongue rolled up like a rope inside the mouth and unfurls it accelerating up to a speed of 13 mph (20 km/h) to attack its victim.

Unlike fish, shrimp do not have fins to swim. To move around in water, it pulls its abdomen toward its body and creates a motion that makes it shoot through water. Because of its body configuration this movement is always backward.

Considered the fastest fish in the ocean, its speed is as much as that of a running cheetah, the fastest land animal. This speed is facilitated by its hydrodynamic shape, a giant dorsal fin and a long, pointy nose.

Sea horses are the only animals in the entire world whose male members carry their young rather than the females. While mating, the female leaves the eggs in the small pouch of the male, thereby making it pregnant. This leaves the female free to make more eggs and reproduce at a faster rate.

To survive through winters, tree frogs "freeze" and come back to life as soon as spring arrives. Commonly known as estivation, this technique includes finding a crevice and building a cocoon around their body, leaving only the nostrils exposed.

Like humans, horses use facial expressions to communicate with each other. They move the muscles around the nostrils, lips and eyes to create different expressions that help them, in a way, talk to each other. As of now, 17 different horse expressions have been identified.

Dolphins have developed a unique sleep pattern that allows them to sleep with one eye open and one hemisphere of their brain still active. The other half of the brain keeps a vigil of the surrounding environment and breathing functions.

#32 -- I think some scientists need to recheck their math... There are 24 hours in a day, each 60 minutes long, so there are 1440 minutes in a day. If the average session is 17 minutes long, than a lioness would be able to mate 84 times in a day and have 12 minutes leftover to eat, sleep, etc.
